Answer:

Choice D.

None of the above.

Explanation:

Standard form of polynomial is written as variable power in a decreasing order as shown below.


ax^(n)+ bx^((n-1)) +cx^((n-2))+............+x^(0)

Here the power of x is decreasing from n to 0

So,

5-2x can be written as


-2x^(1) +5x^(0)

x^4-8x^2-16 can be written as


x^(4)+0x^(3)-8x^(2) +0x^(1)-16x^(0)

5x^3+4x^4-3x+1 can be written as


4x^(4) +5x^(3)+0x^(2)+3x^(1) + 1x^(0)

Note:
x^(0) =1
